The Kremlin said on June 5 that a statement by U.S. national-security adviser Jake Sullivan calling for bilateral arms control discussions was "positive", and that Russia remained open for dialogue. Sullivan said on June 2 that the United States would abide by the nuclear weapons limits set in the New START treaty, the last remaining nuclear arms reduction pact between the two Cold War rivals, until it expired in 2026 if Russia did the same. President Vladimir Putin suspended Moscow's participation in the treaty in February.
